Eugène Louis Melchior Patrin (3 April 1742, Lyon – 15 August 1815, Saint-Vallier) was a French mineralogist and naturalist.
He extensively travelled the Urals, the Altai Mountains and other areas of Siberia, with his mineral collections being shipped back to St. Petersburg ahead of his return.
Patrin's remaining pieces were subsequently offered to the Jardin du Roi collection in Paris, provided that the group not be broken up.
[3] He made important contributions regarding the "mineralogy section" of Buffon's massive work on natural history, "Histoire Naturelle".
[6] The plant genus Patrinia (family Valerianaceae) was named in his honor by Antoine Laurent de Jussieu.
